Universal Analytics for PHP

This library provides a PHP interface to Google Analytics, supporting the Universal Analytics Measurement Protocol, with an interface modeled (loosely) after Google's analytics.js. Future releases will support an interface similar to ga.js, for legacy implementations which already integrate our legacy library.

NOTE that this project is still beta; some features of the Measurement Protocol aren't fully represented, and new features will be added in the (hopefully) nearer future. Please feel free to file issues for feature requests.

Usage

For the most accurate data in your reports, Analytics Pros recommends establishing a distinct ID for each of your users, and integrating that ID on your front-end web tracking, as well as back-end tracking calls. This provides for a consistent, correct representation of user engagement, without skewing overall visit metrics (and others).

A few simple examples:

<?php

require('universal-analytics.php');

$t = new Tracker(/* web property id */ 'UA-XXXXX-Y', /* client id */ 'abc', /* user id */ null);

// Set a custom dimension
$t->set('dimension1', 'pizza');

// Send an event
$t->send(/* hit type */ 'event', /* hit properties */ array(
  'eventCategory' => 'test events',
  'eventAction' => 'testing',
  'eventLabel' => '(test)'
));


// Send a transaction
$tracker->send('transaction', array(
  'transactionId' => $transaction_id,
  'transactionAffiliation' => $affiliate,
  'transactionRevenue' => $total_revenue, // not including tax or shipping
  'transactionShipping' => $total_shipping,
  'transactionTax' => $total_tax
));

// Send an item record related to the preceding transaction
$tracker->send('item', array(
  'transactionId' => $transaction_id,
  'itemName' => $item_name,
  'itemCode' => $item_sku,
  'itemCategory' => $item_variation,
  'itemPrice' => $item_unit_price,
  'itemQuantity' => 1
));


?>

All messages will be flushed when the tracker object is destroyed.

Currently all tracking hits (using send) require an array (dictionary) of properties related to the hit type.

Features not implemented

• Throttling
• GA Classic interface

We're particularly interested in the scope of throttling for back-end tracking for users who have a defined use-case for it. Please contact us if you have such a use-case.
